<br /><br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Hmm, I'm just trying to run one of the "android-ready" examples from Qt, I would expect that they work. It also crashes if my main() doesn't actually do anything.</p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Some more info:</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">something at least already succeeded before:</p>

<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Then there are some other error messages which don't look good:</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"><br /><span style="color:#000000;"><span style="background-color:#ffffff;">W project.exampl: Accessing hidden field Landroid/graphics/drawable/GradientDrawable$GradientState;->mShape:I (greylist-max-p, reflection, denied) </span></span><br />W System.err: java.lang.NoSuchFieldException: mShape <br />0W System.err: at java.lang.Class.getField(Class.java:1604) <br />W System.err: at org.qtproject.qt5.android.ExtractStyle.getGradientDrawable(ExtractStyle.java:672) <br />W System.err: at org.qtproject.qt5.android.ExtractStyle.getDrawable(ExtractStyle.java:1039)<br /></p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">NullPointerExceptions also looks suspicious:</p>

<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">The malloc(4GB)-call and crash happen afterward.</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"><br /></p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">I'm also trying to get some logging output:</p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">int main(int argc, char* argv[])</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">{</p>

<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"> QGuiApplication app(argc,argv);</p>
<br /><br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">but this doesn't seem to appear in logcat. Or do I have to use special options for logcat to see this ?</p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Thanks</p>
